Dry Ice

That lab was so much fun. I felt like a witch with her cauldron. I knew that dry ice would create a kind of smoke but that was just really cool. I never knew that the ice was that cold. I mean you said that it would freeze your hand if you left it there for more than a second. That's dangerous but really cool. I also like that the bubble could float at the tank. I was just watching it from afar but it was pretty cool. I just use to it popping after a couple of seconds in the air. I also loved the bowl of dry ice and hot water. It was so much fun because of the bubble it created. When it popped I was expecting it to like fly everywhere but it just popped and everything gushed out. That was really cool.
